Or just use D. I don''t know if it supports what you''re trying to do (somehow I doubt it). The real question is why do you need a virtual Init function when you can put the contents of the derived Init into a constructor?

This belief is why you aren''t using c++ well. Clear your mind of this, and everything else will be easier.

It makes perfectly good sense for the object to be an A before and during the construction of its A-ness.

char a[99999],*p=a;int main(int c,char**V){char*v=c>0?1[V]:(char*)V;if(c>=0)for(;*v&&93!=*v;){62==*v&&++p||60==*v&&--p||43==*v&&++*p||45==*v&&--*p||44==*v&&(*p=getchar())||46==*v&&putchar(*p)||91==*v&&(*p&&main(0,(char**)(--v+2))||(v=(char*)main(-1,(char**)++v)-1));++v;}else for(c=1;c;c+=(91==*v)-(93==*v),++v);return(int)v;}  /*** drpizza@battleaxe.net ***/

Yeah. Gee. C++ is hard. Ya''ll should just give up when things are hard.

On a serious note, I''ll agree that there are some brilliantly stupid things in C++, but this isn''t one of them.
